The price comes first

Every job starts with a look at the problem and a written quote. You approve the number before any work is scheduled, and the invoice matches the quote. If something changes once a wall is open, you hear about it before we go further.

  • Written quotes. The cost of the visit before it's booked, and the cost of the repair before it starts.
  • Online booking. Pick a time, get a text confirmation, get another text when we're on the way. Pay by card on site.
  • Denver experience. Hundred-year-old bungalows, slab-on-grade ranches, and gas water heaters that have to be set up for 5,280 feet.
  • Repair and remodel. The same crew that fixes a running toilet handles the plumbing on a full kitchen or bath remodel.

Questions people ask

Do you charge a trip fee?

You'll know what the visit costs before it's booked. The repair itself is quoted separately, in writing, before any work starts.

Where do you work?

Denver and the surrounding metro: Aurora, Lakewood, Arvada, Littleton, Westminster, Englewood, Thornton and the cities in between. If it's a reasonable drive from Denver, call.

Can I book online?

Yes. Pick a time on the booking page and you'll get a text confirmation, then another text when we're on the way. Calls and texts to (720) 430-5366 work too.

Do you pull permits?

Yes, wherever the city requires one. Water heater replacements and remodel plumbing are permitted and inspected, and the permit is part of the quoted price.

Do you do emergency calls?

Active leaks get priority on the schedule. If water is running where it shouldn't, shut off the main and call rather than filling out the form.
